Elaphrinae
Guides
Blethisa
Blethisa is a genus of ground beetles in the family Carabidae, subfamily Elaphrinae. It comprises approximately nine extant species distributed across the Holarctic region, plus one fossil species from the Pleistocene. Members of this genus are associated with aquatic or semi-aquatic habitats, with documented diving behavior in at least one species.
Blethisa oregonensis
Blethisa oregonensis is a species of ground beetle in the family Carabidae, first described by LeConte in 1853. The species is found in North America, with distribution records from Canada and the United States. It belongs to the subfamily Elaphrinae, a group of ground beetles often associated with riparian and wetland habitats.
Diacheila
Diacheila is a genus of ground beetles in the family Carabidae, subfamily Elaphrinae. The genus comprises at least four described species, including one extinct species. Members are distributed across Holarctic regions, with some species restricted to Central Asia. The genus is notable for its Arctic and Subarctic specialization, particularly the well-studied D. polita, which exhibits photoperiod-driven life cycle timing.
Diacheila arctica
Arctic Diacheila
Diacheila arctica is a species of ground beetle in the family Carabidae. It has a Holarctic distribution, occurring in Europe, Northern Asia (excluding China), and North America. The species is classified within the subfamily Elaphrinae, a group of small to medium-sized carabid beetles often associated with moist habitats. Two subspecies are recognized: D. a. arctica (Gyllenhal, 1810) and D. a. amoena (Faldermann, 1835).
Elaphrus
Marsh Ground Beetles
Elaphrus is a genus of ground beetles (Carabidae: Elaphrinae) commonly known as marsh ground beetles. The genus contains at least 40 described species distributed across the Palearctic, Nearctic, Near East, and Northern Africa. Many species are strongly associated with wetland habitats, including vernal pools and marshes. Several species exhibit strong morphological resemblance to tiger beetles (Cicindelinae), frequently leading to misidentification by collectors. At least two species, E. viridis and E. sugai, are considered threatened or endangered due to habitat loss and degradation.
Elaphrus americanus
Elaphrus americanus is a ground beetle species in the subfamily Elaphrinae, described by Dejean in 1831. The species occurs across much of Canada and parts of the United States. Members of the genus Elaphrus are frequently mistaken for tiger beetles (Cicindelinae) due to their similar appearance, though they are true ground beetles (Carabidae). Taxonomic analysis has identified this species as part of a complex that includes E. finitimus and multiple subspecies with distinct geographic distributions.
Elaphrus cicatricosus
Elaphrus cicatricosus is a species of ground beetle in the subfamily Elaphrinae, described by John Lawrence LeConte in 1848. It is native to North America, with records from Canada and the United States. The genus Elaphrus comprises beetles that are frequently mistaken for tiger beetles (Cicindelinae) due to their similar appearance and ground-dwelling habits.
Elaphrus lecontei
Elaphrus lecontei is a species of ground beetle in the subfamily Elaphrinae, described by Crotch in 1876. The genus Elaphrus comprises true ground beetles that are frequently mistaken for tiger beetles (Cicindelinae) due to their similar appearance and behavior. These beetles are known for their metallic coloration and preference for moist, sandy habitats.
Elaphrus lindrothi
Elaphrus lindrothi is a species of ground beetle in the subfamily Elaphrinae, described by Goulet in 1983. It belongs to a genus known for species that closely resemble tiger beetles (Cicindelinae), often leading to misidentification by collectors. The species is native to the United States and is part of the North American fauna of Elaphrus, a genus of true ground beetles (Carabidae) with distinctive morphological adaptations.
Elaphrus ruscarius
Shore Ground Beetle
A species of ground beetle in the subfamily Elaphrinae, described by Thomas Say in 1834. Like other members of the genus Elaphrus, it bears a strong resemblance to tiger beetles (Cicindelinae), which can mislead collectors. The genus is known for its preference for moist habitats near water.
